1-6 Technical Information
Chipset
The Image P90E and Image P100E computers use the Intel Neptune II chipset, which consists of the PCI cache and memory controller (PCMC), two local bus accelerators (LBXs), the PCI EISA bridge component (PCEB), and the EISA system component (ESC). Together these five chips control the cache memory, the EISA bus, the BIOS Flash ROM, the keyboard controller, and the I/O controller. The chipset also contains several I/O ports that control many aspects of the computer’s hardware operation.
PCI Cache and Memory Controller (PCMC)
The PCMC provides cache control, system memory control, and PCI bus control. An integrated cache controller supports 256 KB of synchronous SRAM. The PCMC supports up to 256 MBs of cacheable system memory. The PCI controller enhances system memory performance by allowing for concurrency between the CPU bus and the PCI bus. For further details, refer to the Intel Neptune II PCMC and LBX Component Specification.
Local Bus Accelerators (LBXs)
Two LBXs are used to interface the Host bus to the PCI bus and the system memory data bus. The LBXs provide the following five buffers to increase performance.
n CPU to memory posted write buffer n PCI to memory posted write buffer n Memory to PCI read buffer n CPU to PCI posted write buffer n CPU to PCI read prefetch buffer
For further details, refer to the Intel Neptune II PCMC and LBX Component Specification.
Page 23
Technical Information 1-7
PCI-EISA Bridge Component (PCEB)
The PCEB is one of the two chips that connect the PCI bus to to the EISA bus. The PCEB translates bus protocols from EISA to PCI and vice versa. Extensive buffering of both the PCI and EISA interface allows for concurrent operations. Address decoding is provided for both PCI and EISA. For further details, refer to the Intel PCI–EISA Bridge (PCEB) Component Specification.
EISA System Component (ESC)
The ESC interfaces the PCI bus to the EISA bus. The ESC supplements the PCEB by implementing such system functions as the Timer/ Counter, DMA and interrupt controllers, and EISA subsystem control functions (such as the Bus Controller and Bus Arbiter). Interrupt level assignments are provided later in this section (see “Interrupt Controller”). For further details, refer to the Intel EISA System Component (ESC) Specification.
Bus Architecture
The interconnection of the major system components via the address and data buses is shown in Figure Section 1-2. The number range next to each bus arrow indicates the bits on the bus the arrow represents. Major buses include the host bus, system memory bus, the PCI bus, the EISA bus, and the XD bus. The function of these buses is described in the following subsections.
Page 24
1-8 Technical Information
Figure Section 1-2 Component Block Diagram
Host Bus
The host bus consists of a 32-bit address bus (A<31..0>), a 64-bit data bus (D<63..0>), and control circuitry. The host bus interfaces the processor to the PCI cache and memory controller (PCMC), the local bus accelerators (LBXs), and the secondary (L2) cache. Host bus cycles are initiated by ADS* signals from the processor and terminated by BRDY* signal from the PCMC. All host bus cycles are monitored by the PCMC and directed to the cache, system memory, or the PCI bus.
Page 25
Technical Information 1-9
PCI Bus
The PCI bus consists of a multiplexed address and data bus (AD<31..0>) and control circuitry. The PCI bus allows industry-standard PCI option boards to interface to the system. The PCMC and LBXs link the PCI bus to the host bus, and PCI EISA bridge component (PCEB) links the PCI bus to the EISA bus. PCI is a high bandwidth bus that is processor independent. The on-board video, IDE, and SCSI controllers are on the PCI bus.
EISA Bus
The EISA bus consists of an address bus (SA<19..0>, LA<31..24>*, and <LA23..2>), a 32­bit data bus (SD<31..0>), and control circuitry. The EISA bus is controlled by the PCEB and EISA System component (ESC) and provides connection to industry standard EISA/ISA option boards.
XD Bus
The XD bus (XD<7..0>) is an 8 bit data bus that provides connection to the keyboard controller, ROM BIOS, and real-time clock (RTC). The XD bus is a buffered version of the low order 8 bits of the EISA data bus (SD<31..0>). In the Neptune chipset, a distinction is made between on-board and off-board peripherals. In general, on-board means that access is expected to occur via the XD bus instead of the EISA bus. In this case, the access still occurs on the EISA bus, but if the access is a read (I/O or memory), the ESC enables the XD bus peripheral to drive the lower 8 bits of the EISA data bus (SD<7..0>).
System Memory Bus
The system memory bus consists of 11 bits of row/column addresses (MA<10..0>) that are buffered to address banks 0, 1, 2, and 3. Each bank consists of two SIMMs. The PCMC drives the system memory bus and memory control signals, which causes the data to be driven to/from the LBXs (MD<63..0>).
Processor
The Image P90 system uses a 64-bit, 90-MHz Pentium microprocessor with a 60-MHz external clock speed. The Image P100E uses a 64-bit, 100-MHz Pentium microprocessor with a 66-MHz external clock speed. The technology package used for the microprocessor is the 296-pin, staggered-pin-grid array (SPGA. The processor has 16 KB of write-back internal cache, 8 KB for instructions and 8 KB for data. Also integrated into the processor is a math coprocessor for complex calculations and processing tasks.
To use the Pentium processor’s power, the system features an optimized 64-bit memory interface and complementary 256-KB secondary cache.
The Pentium processor is compatible with all 8-, 16-, and 32-bit software written for the Intel386™, Intel486™, and Pentium processors.
Page 26
1-10 Technical Information
The dual processor upgrade option is installed in a 320-pin PGA, zero-insertion-force (ZIF) socket on the system board.
Secondary Cache
The 16-KB primary cache (8 KB data and 8 KB instruction) is integrated into the processor. The system board also provides 256 KB of 9-ns, synchronous secondary cache memory that is external to the processor. Cache memory improves read performance by holding copies of code and data that are frequently requested from the system memory by the processor. Cache memory is not considered part of the expansion memory.
The cache is connected directly to the processor address bus (direct mapped) and uses physical addresses (32-bit line size). A bus feature known as Burst enables fast cache fills. Memory areas (pages) can be designated as cacheable or non-cacheable by software. The cache can also be enabled and disabled by software.
The write strategy of the secondary cache is write-back for single processor systems and write-through for dual processor systems. If the write is a cache hit, an external bus cycle is generated and information is written to the cache. Any area of memory can be cached in the system. Non-cacheable portions of memory are defined by software. The cache can be cleared by software instructions.
Flash ROM
Machine language programs known as the system's basic input/output system (BIOS) are stored in a 256K x 8 Flash ROM chip (28F020 PLCC) mounted on the system board. The system BIOS, EISA extensions, PCI extensions, Automatic Configuration Unit (ACU) loader, and Video BIOS reside in the upper 64K of the ROM area. The lower 64K of ROM includes the SCSI BIOS and ACU code.
The flash ROM allows the BIOS to be upgraded with the BIOS Update utility without removing the ROM (see Section 4, Maintenance and Troubleshooting). The BIOS can only be reprogrammed by powering on the system with the BIOS Update utility diskette in drive A.
The BIOS programs execute the Power-On Self-Test (POST), initialize the processor controllers, and interact with the display, diskette drives, hard disks, communication devices, and peripherals. The system BIOS also contains the Setup program and provides VGA controller support. The ROM BIOS is always copied into RAM (shadowing) for maximum performance.
System BIOS is located between E0000h-FFFFFh and supports shadowing and shadowed memory. System BIOS is write protected and automatically enabled.
The video BIOS is combined with the system BIOS and is located between C0000h and C7FFFh. The system memory map is shown in Table Section 1-2.

Flash ROM supports the reprogramming of the system and built-in video BIOS. The Flash part can be accessed in 128K granularity for ROM reads and 64K granularity for flashing. NEC Port 0C12h bits 6 and 7 map each of the four 64K byte chunks of the ROM to the FXXXX range. ACU access is controlled by the system BIOS code and is generally not accessible in ISA space. Table Section 1-3 shows how to access the different areas of the Flash ROM by using bits 6 and 7 (RPG0 – 1) from NEC proprietary port 0C12h (see “NEC Proprietary Ports” later in this section).

1-12 Technical Information
Flash ROM programming is supported only in the 0F0000h – 0FFFFh area. The system and Video BIOS area of the Flash ROM (upper 64 KB) can be erased, programmed, and verified normally with the RPG0 bit set low (to 0). To erase, program, and verify the SCSI BIOS and ACU area (lower 64 bits) the RPG0 bit must be set high (to 1). This allows access to the lower 64 KB of the Flash ROM via the 0F000h to 0FFFFFh area.
To upgrade the BIOS, see Section 4, Maintenance and Troubleshooting, for BIOS upgrade information.
On-Board Peripherals
The following subsections describe the computer’s on-board peripheral control circuitry. The peripherals interface with the computer through either the PCI or EISA buses.
SCSI Circuitry
The SCSI circuitry is controlled by the Adaptec AIC-7850 PCI bus to SCSI bus controller. SCSI bus connectivity allows connection to SCSI-compatible peripherals, such as high­capacity floppy drives, tape drives, and CD-ROMs. The AIC-7850 can support data transfer rates of up to 10 MBs per second. For further information, refer to the Adaptec AIC-7850 data manual.
IDE Controller
The CMD PCIO640B IDE controller supports up to four IDE hard disks. The PCIO640B supports both primary and secondary IDE devices. Automatic sensing of EISA hard disk controllers is provided. If the BIOS senses an EISA hard disk controller, the on-board IDE interface is disabled. For further information, refer to the CMD PCIO640B data manual.
Video Circuitry
The Tseng W32P PCI graphics accelerator features a graphical user interface (GUI) accelerator and advanced features for the developing imaging and multimedia markets. For further information, refer to the Tseng W32P data manual.
EISA SRAM
A 6264LP 8Kx8 static RAM is used to configure the EISA bus. This SRAM receives its power from the bq4287 real-time clock (RTC), which uses a lithium battery. The 6264LP is located on the EISA bus.
Page 29
Technical Information 1-13
Real-Time Clock (RTC)
The computer uses a Benchmarq bq4287 RTC module with non-volatile RAM control. The bq4287 resides on the XD bus and provides a time-of-day clock and a 100-year calendar with alarm features and battery operation. The battery life is approximately 6 years when driving an SRAM that draws 2 microamperes when off and the computer is off 2/3 of the day. For further information, refer to the Benchmarq bq4287 data sheet.
System I/O Controller
The computer uses the SMC FDC37C665 I/O system I/O controller to provide a floppy disk controller, a digital data separator, two 16550 compatible UARTS, and an enhanced bidirectional parallel port. The computer supports extended capabilities port (ECP), enhanced parallel port (EPP), and ZIPPY protocols.
The I/O controller provides control for up to two diskette/tape drives. The following devices are supported:
n 5 1/4-inch 360 KB diskette drive n 5 1/4-inch 1.2 MB diskette drive n 3 1/2-inch, 720 KB diskette drive n 3 1/2-inch, 1.44 MB diskette drive n 3 1/2-inch 2.88 MB diskette drive
The capacity of 3 1/2 inch diskette drives is sensed automatically. The existence of an EISA floppy controller is also automatically sensed. If the BIOS detects an EISA floppy controller, the on-board floppy controller is disabled. The on-board floppy controller can also be disabled via Setup (for diskless workstations). However, if there is no bootable device available, the system BIOS will attempt to boot from the built-in floppy even if the on-board floppy controller is disabled via Setup. This provides a bootable system in the event that the CMOS is corrupted.
I/O Mapping
The processor communicates with I/O devices by I/O mapping. There are a large number of I/O ports implemented in the system associated with the keyboard controller, system I/O controller, and Neptune II chipset. The hexadecimal (hex) addresses of I/O devices used by the Image P90E and Image P100E are listed in Table Section 1-4. For a description of the chipset configuration registers, see the following subsection.
The I/O ports implemented by the system I/O controller are not listed. Refer to the SMC FDC37C665 data sheets for a detailed description of the system I/O controller ports. In addition, keyboard controller registers (with the exception of the keyboard status register) are documented in the NEC PS/2 Style Keyboard Controller release notes.

System Memory
Image P90E and Image P100E configurations ship with 16 MB of RAM. System memory can be expanded to a maximum of 256 MB. Total address space is 4 gigabytes (GB) maximum. Memory expansion is performed using single in-line memory modules (SIMMs) installed in SIMM sockets on the memory expansion board.
The memory expansion board consists of eight SIMM connectors organized into four banks. All system memory supports parity. Memory shipped with the system is comprised of two 2-MB x 36-bit DRAM SIMM modules (which is 2 x 8MB). The first megabyte includes the standard 640 KB of base memory. The remaining memory is extended memory.
The SIMM memory sockets accept 4-, 8-, 16-, or 32-MB SIMM sticks. High-speed RAM is 32 bits wide with four parity bits. SIMMs are 1 M x 36 bit (4 MB), 2 M x 36 bit (8 MB), 4 M x 36 bit (16 MB), and 8 M x 36 bit (32 MB). There are no switches or jumpers to set when SIMMs are added.
The system board's eight SIMM sockets are assigned as banks 0, 1, 2, and 3. Each SIMM kit is inserted into a pair of sockets or bank. Bank 0 contains the two standard SIMMs shipped with the system. Banks 1, 2, and 3 are available for memory expansion. Different size SIMMs cannot be intermixed within a bank. See Section 3, Options, for installation instructions and SIMM memory configurations.

1-22 Technical Information
Interrupt Controller
The interrupt controller is implemented on the EISA system component (ESC) and operates as an interrupt manager for the entire system environment. The controller accepts requests from peripherals, issues interrupt requests to the processor, resolves interrupt priorities, and provides vectors for the processor to determine which interrupt routine to execute. The interrupt controller has priority assignment modes that can be reconfigured at any time during system operations.
The interrupt levels are listed in Table Section 1-5. Interrupt-level assignments 0 through 15 are in order of decreasing priority. See Section 2, Setup and Configuration, for information on changing the interrupts using Setup.

Video Controller
The Tseng W32P PCI graphics controller is a PCI local bus video controller that delivers a 32-bit PCI-bus interface with the CPU. It features a graphic user interface (GUI) accelerator, and advanced features for imaging and multimedia markets. Multimedia and imaging are enhanced through the inclusion of an unique Image Memory Access (IMA) port that allows direct access to the frame buffer at high speed. The IMA port allows analog motion video to be converted to digital video signals. An 8-bit port into memory allows images to be displayed on screen in real time, at color depths of up to 16.7 million simultaneous.
Video Memory
There are eight 256k x 8, 45 ns DRAM chips soldered on the system board providing 2 MB of video memory. The on-board video DRAM provides graphic support for 640 x 480 and 800 x 600 resolutions with 16.8 million colors, 1024 x 768 resolution with 256 colors, or 1280 x 1024 resolution with 16 colors.
EISA Bus
The system board uses the EISA bus for transferring data between the processor and I/O peripherals and expansion boards. EISA connectors J22 through J25 allow installation of both EISA and ISA expansion boards. The EISA architecture is fully downward compatible with ISA hardware, and EISA boards, unlike ISA boards, require no jumper settings. They are configured through software. A 6264LP 8K x 8 SRAM is used to configure the EISA bus. This SRAM receives power from the bq4287 RTC, which uses a lithium battery. Other EISA features include:
n 32-bit memory addressing for the processor, DMA devices, and bus masters n 8-/16-/32-bit data transfers n 33 MB/sec burst mode data transfer n Addressability up to 4 GB n Efficient synchronous data transfer protocol for normal and high-speed transfers n Automatic bus cycle translation between EISA and ISA masters and slaves n Intelligent bus master peripheral controller support n Enhanced DMA arbitration and transfer rates n Shareable interrupts, programmable for edge or level triggering n Automatic system configuration
The four EISA connectors contain two sets of contacts: one for EISA boards and one for ISA boards. A tab prevents ISA boards from being inserted into the EISA contacts (see Figure Section 1-3).

Various DMA cycle types are needed to cover the speed and complex requirements of different applications. In EISA systems, control signals, address lines, and the data bus use a bus clock generated by the system board as the transfer reference. Since the bus clock is not a fixed frequency, the protocol synchronizes the bus cycles to a common clock to achieve maximum performance.
EISA DMA devices can be programmed for high-performance data transfers using one of four DMA cycle types. Compatible cycles (the default) supply a higher data transfer than ISA. The improvement is the result of EISA faster bus arbitration. Type A and type B cycles permit some ISA-compatible DMA devices to achieve an even higher performance level. The Burst DMA cycle (type C) provides the highest performance cycle and is only available to DMA devices designed specifically for Burst. (Burst cycles require 1 clock per transfer). Table Section 1-6 shows the data transfer rates for each cycle type and the compatible DMA devices.

EISA’s bus master archictecture supports intelligent peripherals. The bus master architecture provides a high-speed data channel with data rates up to 33 MB per second using EISA Burst cycles. The bus master provides local intelligence by including a dedicated I/O processor and local memory. It can relieve the burden on the processor by performing sophisticated memory access functions, such as non-ordered, scatter-gather data transfers.
The EISA bus provides a way for EISA expansion boards and ISA-compatible devices to communicate. EISA data and control signals are generated by the bus master or slave. This lets the system board copy the data to the appropriate byte lanes and translate the control signals. Automatic translation is provided by the system board for DMA devices and 16­and 32-bit EISA devices.
EISA’s centralized arbitration scheme allows efficient bus sharing among multiple EISA bus masters and DMA devices. The centralized arbitration supports preemption of an active bus master or DMA device and can reset a device that does not release the bus after preemption. The bus is granted to DMA devices, DRAM refresh, bus masters, and processor functions on a rotational basis. This rotation provides a short latency for DMA devices to assure ISA compatibility and longer latencies for the bus master and processor.
EISA interrupts can be configured for edge- or level-triggered operation. Edge-triggered operation supplies compatibility with existing, interrupt-driven ISA devices. Level­triggered operation allows the sharing of a single system interrupt by many EISA devices.
Page 42
1-26 Technical Information
PCI Local Bus
The industry-standard PCI-bus is a highly-integrated I/O interface that offers the highest performance local bus available for the Pentium processor. The PCI-bus supports burst modes that send large chunks of data across the bus, allowing fast displays of high­resolution images.
The high-bandwidth PCI-bus eliminates the data bottleneck found in traditional systems, maintains maximum performance at high clock speeds, and provides a clear upgrade path to future technologies. PCI expansion slot connector pin assignments are provided in Appendix B.
PCI Auto Configuration
The system comes with a PCI auto configuration utility that operates in conjunction with the system’s Setup utility. The utilities automatically configure interrupts, DMA channels, I/O space, and other parameters to allow addition of PCI boards with minimal intervention.
Parallel Interface
The I/O controller provides a programmable bi-directional printer port that can can be configured as EPP, ECP, or PS/2 compatible.
The BIOS has automatic EISA printer port sensing. If the BIOS detects an EISA printer port mapped to the same address, the built-in printer port is disabled. The BIOS also sets the first parallel interface port it finds as LPT1 and the second port it finds as LPT2. The interrupt is selected to either IRQ5 or IRQ7 via the Setup.
Interrupt levels for the parallel port are given in Table Section 1-7. Software selectable base addresses are 3BCh, 378h, and 278h.
Parallel interface signals are output through the system board's 25-pin, D-subconnector. The connector is located at the rear of the system unit. Pin locations for the parallel interface connector are shown in Appendix B.
The printer port base address and interrupt request can be independently disabled. It is the responsibility of the system BIOS to ensure that the base address or interrupt request line used by a parallel port is not used by the EISA bus (or conflicts will result).

Technical Information 1-27
Serial Interface
The system has two standard serial ports. The serial ports support the standard RS-232C interface. The interrupt is selectable via Setup. Serial interface signals are output through the system board's 9-pin, D-subconnector. The connectors are located at the rear of the system unit. Pin locations for the serial interface connector are shown in Appendix B
Each of the two serial ports can be configured as COM1, COM2, COM3, or COM4. The options for the base address and interrupt request that can be selected are provided in Table Section 1-8. The primary serial port (P3) defaults to COM1, IRQ3. The secondary serial port defaults to COM2, IRQ4. Note that the I/O controller supports the mapping of any of these logical ports to either physical port. Additionally, each serial port can be independently disabled. It is the responsibility of the system BIOS to ensure that the base address or interrupt request line used by a serial port is not used by the EISA bus (or conflicts will result).

Indicator Panel
The indicator panel is attached to the front panel and contains the power lamp, hard disk drive busy lamp, and reset button. The indicator panel attaches to the system board using connector J4 (reset connector), J12 (power lamp connector), and J11 (hard disk drive busy lamp connector).
Power Supply
The power supply is mounted inside the system unit. It supplies power to the system board (+5V, +12V, and -12V), and storage devices. In turn, the system board supplies power to the keyboard, mouse, and any installed expansion boards. (-5V is provided to EISA adapter boards, but this voltage is not used by the system board.) Three connectors connect the power supply to the system board (connectors J17, J21, and J31). There are also connectors available for the six possible storage devices.
A fan inside the power supply (at connectors J6 and J7) provides proper ventilation for the system. The power supply provides 260W of power. Power requirements and specifications for the power supply are provided in Appendix A, Specifications.
Diskette Drive
The computer supports up to two diskette drives. Image P90E and Image P100E systems ship with one standard diskette drive that connects to the system board by means of a single-connector ribbon cable. To install a second, optional diskette drive, a single ribbon cable with two drive connectors must be installed in place of the single-connector cable. The dual-connector cable option is available from NEC (see Section 4). The system refers to the diskette drives as A and B. Drive A is for the first drive, B is for the second optional diskette drive. Typically, both diskette drives are terminated. See Section 3, Options, for instructions on installing an optional 5 1/4-inch diskette drive (or 3 1/2-inch diskette drive in a 5 1/4-inch form factor). Specifications for the diskette drives are provided in Appendix A, Specifications.
Hard Disk Drive
The system provides two fast PCI-bus IDE interface connectors on the system board. The system board supports one or two devices on each IDE connector. The system also provides one SCSI connector supporting up to five internal and 7 external devices (hard disk drives, tape back-up drives, and CD ROM readers) using the PCI local bus Fast SCSI-2 host adapter.
The system unit provides two internal storage slots (one 1-inch height and one 1.6-inch height) for 3 1/2-inch hard disk drives. When configurations are shipped with a hard disk drive, one of these slots is occupied. Three accessible 5 1/4-inch device (1.6-inch height) storage slots also available for optional devices. See Section 3, Options, for installing an optional hard disk drive. Specifications for the hard drives are provided in Appendix A, Specifications.

SETTING SYSTEM PARAMETERS
This subsection describes the utilities that allow you to view and change system configuration information and control special features of the system. The utilities include:
n ROM-based Setup utility — use this utility to set system parameters such as date,
time, and system security features. You can also use the utility for configuring optional PCI and IDE devices or to check or change the video device.
n EISA Configuration utility (ECU) — use this utility when adding, moving,
removing, or configuring any optional EISA, PCI, Plug and Play ISA, or non­Plug and Play ISA expansion boards.
n SCSI Select™ utility — use this utility to check the settings of your installed
SCSI-2 devices or to configure the system for any optional SCSI devices that you may install.
NOTE: Your system ships from the factory with the correct system parameters for your configuration. Unless you add optional hardware, you do not need to run the Setup, ECU, or SCSI Select utilities to operate your system.
However, you might wish to run Setup to set features that customize your system, such as time, date, and security. The system ships from the factory with the correct system configuration for each system.
System configuration information is stored in nonvolatile memory (NVRAM). Nonvolatile memory in the system is a complementary metal-oxide semiconductor (CMOS) chip, backed up by the RTC/battery module on the system board. The RTC battery supplies continuous power to the CMOS memory and maintains configuration information when system power is off.
NOTE: NEC recommends that you print out or
write down your current Setup parameters and store the information in a safe place. This lets you restore your system to the current parameters if you ever need to replace the RTC/battery module (see Section 4 for replacement procedures).
Page 51
2-6 Setup and Operation
SETUP UTILITY
The Setup utility is used to view and set system parameters. Use the Setup utility program to:
n set the time and date. n check or change the diskette drive type. n update or check system parameters when you add or remove PCI/IDE expansion
options.
n check or change the video device. n check or update memory cache or shadow settings. n check or update the system’s boot sequence. n check or update keyboard settings. n check the installation of optional memory by comparing the amount of memory
installed with the amount of memory displayed by Setup.
n customize your system with security features such as Supervisor and user login
IDs and passwords.
n correct a hardware discrepancy when the Power-On-Self-Test (POST) displays an
error message and prompts you to run Setup.
n reset system parameters in the event that you need to replace the RTC/battery
module
n reset system parameters after clearing CMOS.

Plug and Play OS Parameters
The system comes with Plug and Play system support already installed and ready for installation of a plug and play operating system (O/S). With this support, the system automatically configures newly added ISA Plug and Play cards. You only need to install the board and boot the system. The system automatically allocates resources to the board.
Plug and Play boards are industry-standard architecture (ISA) boards with Plug and Play capability. You can enable Plug and Play directly from the Advanced menu using the command keys. Selecting “Yes” from the menu enables the Plug and Play option (see Table Section 2-11). “No” is the default setting, as most current ISA boards do not have Plug and Play capability. However, you can include them in your system, with or without Plug and Play capabilities.
To work in a system, boards often use a variety of dedicated resources. If two boards try to use the same resource, one board might not work or errors may occur.
NOTE: Generally, a resource can be used by only one board or device. However, some boards can share the same DMA or IRQ resources. Review the board manufacturer's documentation to see if the board supports shared resources.
Page 67
2-22 Setup and Operation
Plug and Play boards are dynamic in nature — the system allocates resources to these boards upon system boot (Table Section 2-11). Some device drivers support this dynamic board configuration, but some do not.
Device drivers that do not support the dynamic board configuration are also known as static device drivers. If using a static device driver, you need to permanently associate resources assigned with a Plug and Play board, instead of relying on the Plug and Play default. Otherwise, the device driver might not be able to find the board the next time the system boots.
Table Section 2-11 Plug and Play Parameters
Parameter Options Description
Plug and Play O/S Yes
No (default)
Selects the Plug and Play feature which automatically assigns the address and interrupt for added options. Functions only for Plug and Play operating systems.
PCI Device Parameters
Select the PCI Devices parameter if you need to allocate I/O resources (see Table Section 2-12). The combed I/O resource allocation parameter default setting is disabled. The parameter should be enabled only when a non-plug and play board is not working due to I/O space resource conflicts. This is particuliarly true for older boards using 10-bit I/O space decoders rather than the full 16-bit I/O space.
Use the legend keys to make your selections and exit to the main menu.

EISA Configuration Utility
The ECU program comes on a diskette that ships with the computer and is required for EISA configuration. The ECU provides a detailed view of the system configuration and allows you to make system configuration changes when you add, move, or remove an EISA or ISA expansion board.
Use the ECU program when you are setting up the system for the first time and whenever you add an EISA, ISA, PCI, or Plug and Play ISA board to fully configure the system. This ensures that the information in the system's complementary metal oxide semiconductor (CMOS ) is consistent with the configuration information stored in the BIOS.
The ECU
When you add a board to your configuration and run the ECU program, the utility reads the board’s corresponding configuration (CFG) file. The ECU uses the CFG file, which describes the characteristics and the required system resources of the board, to create a conflict-free configuration.
Once you complete the configuration process, configuration information is saved to the system’s nonvolatile memory for use any time you power-on the system.
The ECU includes the following features:
n Supports EISA and ISA boards, PCI devices, and Plug and Play boards. n Automatically detects EISA boards, PCI devices, and Plug and Play ISA boards
installed in your computer.
n Helps you configure ISA boards by providing the approprate switch and jumper
settings.
n Creates and maintains the System Configuration Information (SCI) file as a
backup for the computer’s nonvolatile memory.
n Supports configuration (CFG) file extensions. n Lets you set the computer’s date and time.
The ECU program comes on the EISA Configuration Utility diskette that ships with your system.
NOTE: Do not execute the EISA Configuration Utility from your hard disk. The utility program must start with a cold boot from the EISA Con­figuration Utility diskette.
Page 78
Setup and Operation 2-33
When to Use the ECU
Run the ECU the first time you set up your system and any time you add, remove, or move an EISA or ISA board in the computer. You must physically install the boards in the com­puter and add the configuration information stored in the computer by the ECU.
NOTE: You must install an EISA, PCI, or Plug and Play board or device before running the ECU utility. If installing a non-Plug and Play ISA board, it must be installed after running the ECU utility.
Use the ECU to :
n change or check system parameters when you add, move, or remove an expan-
sion board.
n print out the required settings of a particular board or option. n correct a hardware discrepancy when the Power-On Self-Test (POST) displays
an “Invalid EISA Configuration Storage - RUN ECU” error message and prompts you to run the ECU program.
n boot the system and check parameters when you have a problem booting the
system.
n change functions and resources of boards installed in the system. n resolve a resource conflict when adding a board or changing a board function or
resource.
n lock and unlock boards in the configuration. n maintain the ECU Utility diskette. n set system parameters when the real time clock (RTC)/battery module is re-
placed.
How to Load the ECU
Use the following steps to load the ECU.
1. With the system power off, insert the NEC EISA Configuration Utility diskette
into diskette drive A. The ECU requires a cold boot each time you load it.
2. Power on the system. After performing its Power-On Self-Test, the system loads
and starts the ECU. An ECU preparation screen appears followed by the NEC logo screen and the Main Menu (see Figure Section 2-4).

Setup and Operation 2-35
Configure Computer or Peripheral Devices
Select the “Configure Computer or Peripheral Devices” option under the following cir­cumstances:
n you are setting up the system for the first time n the “Invalid Configuration Information” message appears at power-on.
If this message appears, run the Setup utility to correct any configuration errors. If you receive an “EISA Configuration NVRAM Bad - Run Configuration utility
- F2 to Run Setup” message, run Setup first, then the ECU utility.
n you add or remove an expansion board n you installed a PCI, EISA, ISA, or Plug and Play device n you want to change board functions or resources n you want to view switch and jumper settings for a specific board n you replaced the RTC/battery module in the system and need to set the system
parameters.
If you installed an EISA or ISA board and you select “Configure Computer or Peripheral Devices,” the ECU might display an “Automatic Add” screen with a request for a configu­ration (CFG) file.
The ECU displays this screen if it needs a configuration (CFG) file for the installed board. If the screen appears, remove the ECU diskette and insert the diskette containing the CFG file. Press Enter and follow the screen prompts to automatically add the required CFG file.
NOTE: EISA and ISA boards require CFG files for system configuration. The board manufac­turer supplies the CFG file for an EISA board. Some ISA boards also come with a CFG file. If you have an ISA board that does not have a CFG file, see “ISA Boards without CFG Files” in this section.
If the ECU does not need any configuration files, it displays a menu with five steps for configuring your computer:
Step 1: Important EISA configuration information — provides EISA configuration infor­mation.
Step 2: Add or remove boards — configures the system for the addition or removal of an expansion board to or from the system.
Page 81
2-36 Setup and Operation
Step 3: View or edit details — lets you view and change system board settings. You must select this step when you are setting up the system for the first time.
Step 4: Examine switches or print report — allows you to view the required switch and jumper settings of a particular board. You can also select a print option to print the required settings of a particular board.
Step 5: Save and exit — lets you save the system configuration and exit the utility.
NOTE: If you are setting up the system for the first time, you must select Step 3, even if you did not install an expansion board. This step config­ures the system board in your system.
The following subsections describe each of the configuration steps in sequence.
(1) Step 1: Important EISA Configuration Information
Select Step 1 for information about using the ECU to configure your EISA system.
NOTE: It is recommended that you select Step 1 before continuing with the ECU utility. Step 1 contains an overview of the process for selecting and configuring EISA or ISA expansion boards.

ISA Boards without CFG Files
If a CFG file did not ship with your ISA board, check to see if one exists for the board on the ECU diskette or on a CFG File Library diskette. If you still cannot locate a CFG file for the board, use one of the following procedures:
n configure your system for the ISA board with the Generic ISA CFG File pro-
vided by the ECU (see the next subsection, “Using the Generic ISA CFG File”).
n create a CFG file for the ISA board (see “Using the Create CFG File Facility”
later in this section). Use this procedure when the Generic ISA CFG File is not available.
(1) Using the Generic ISA CFG File
The ECU provides one Generic ISA CFG file that you can use with an ISA board that does not have a corresponding file. However, if you have a multifunction ISA board, you may have to manually create a configuration file (see “Using the Create CFG File Facility”).
NOTE: The ECU provides only one Generic ISA CFG file. If you already used the Generic ISA CFG file, see the next subsection, “Using the Create CFG File Facility.”
Before you use the Generic ISA CFG file, determine if a CFG file exists for the ISA board. If you cannot locate a CFG file, use the following procedure to configure your system for the ISA board.
NOTE: Do not install the ISA board in the computer until you have completed the follow­ing procedure.
1. Locate the manufacturer’s documentation that comes with the ISA board. This
document provides information about any required resources for the ISA board.
2. Run the ECU utility and select “Configure Computer or Peripheral Devices”
from the Main Menu.
3. Select “Step 2: Add or remove boards.”
4. Press Insert to select the Add function. A message appears telling you to locate
the CFG file for the board you want to install.
5. Press Enter. The “Select a Configuration (CFG) file to add” screen appears.
